context.</p>
<p>QDeclarativeScriptString is used to create <a href="qobject.html">QObject</a> properties that accept a script
"assignment" from QML.</p>
<p>Normally, the following QML would result in a binding being
established for the <tt>script</tt> property; i.e. <tt>script</tt>
would be assigned the value obtained from running <tt>myObj.value =
Math.max(myValue, 100)</tt></p>
<pre class="qml">
<span class="type">MyType</span> {
<span class="name">script</span>: <span class="name">myObj</span>.<span class="name">value</span> <span class="operator">=</span> <span class="name">Math</span>.<span class="name">max</span>(<span class="name">myValue</span>, <span class="number">100</span>)
}
</pre>
<p>If instead the property had a type of QDeclarativeScriptString,
the script itself -- <i>myObj.value = Math.max(myValue, 100)</i> --
would be passed to the <tt>script</tt> property and the class could
choose how to handle it. Typically, the class will evaluate the
script at some later time using a <a href="qdeclarativeexpression.html">QDeclarativeExpression</a>.</p>
<pre class="cpp">
<span class="type"><a href="qdeclarativeexpression.html">QDeclarativeExpression</a></span> expr(scriptString<span class="operator">.</span>context()<span class="operator">,</span> scriptString<span class="operator">.</span>script()<span class="operator">,</span> scriptStr<span class="operator">.</span>scopeObject());
expr<span class="operator">.</span>value();
